Political asylum in Cuba.

Suppose a communist in an imperialist country is politically prosecuted (prison, maybe death sentence) because of their political work, so they try to get the hell out of there. As a faithful Marxist-Leninist, they love Cuba, so they want to go there. Would Cuba harbor a comrade in need of help, or would they extradite?

They're constitutionally bound to. Cuba granted political asylum to many comrades from the ANC and other African liberation movements, as well as some of those targetted in the US (like the Black Panthers and I think one or two of the Weathermen).

The moment one accepts the notion of 'totalitarianism', one is firmly locked within the liberal-democratic horizon. - Slavoj Žižek
